The A4000T is an awesome machine supplying you with almost everything you need when combined with a Cyberstorm PPC card. However, there are two disadvantages to this wonderful machine:
1. You CPU card is hanging vertically, which makes it easier to damage heavy cards (such as the Cyberstorm PPC) without doing anything. This problem may become bigger after a year or two, we have had the problem several times already.
2. The power plug on the mainboard (P8/P9 AT plug) may get brown after leaving the machine on for a very long time. Depending on how long the machine is used, it may even melt after less than a year. This problem is hard to solve, but if you clean the connector very well, it may take much longer (or never) before it happens.
